| Abstract | A new type of mass changing oscillation system was investigated,
where the mass is a function of space. Namely, if a mass is oscillated in the water in the vicinity of a boundary, the virtual mass must change with respect to the distance between the mass and the boundary. As a system, a sphere with a leaf spring, oscillating
in the neighborhood of a wall, was chosen which is considered as
simplified ocean structure system.
Experimental results showed that the frequency of the oscillation changes with respect to time if there is a wall. The change is predominate as the wall distance becomes smaller. The similar thing happens for the smaller density of the sphere. for a specified wall distance. Solutions obtained from numerical and perturbation methods gave a good agreement with the experimental results except in the initial stage of the oscillation. Phase-plane analysis
showed that the solution is stable and periodic. |
